15 It is well known thalfto sustain an aeropla-ne the upward pressureol? the air upon lts planes moet; he equal .in li'oreey 'to the Weightof the machine. From this it will be readily appreciated that the, shapeand curvature of the planes upon which the air pressure is directed isof utmost importar-lire and it is my aim to provide planes designed soas to :secure the utmost lifting; power with the minimum amount of airpressure.

In carrying out my invention, I provide a transverse plane7 which willbe termed a ear rier, plane, haring' a eonenre upper surl'zmo, and guideplanen seein-srl at their edgar; afl-- ja'eent the forward ends thereohto the transverse pinnev said ,guide planes conrergiine' rear-wardly andbeing eo'nneetfnl to eaeh other at their rear extremitiee. rlhefsetfHf-l planes are ilonhly ein-ved7 hai/iin; their upper surfacesadjacent their forward ends concave, and adgaeent their rear ends con-Vex. This structure insnree` a steady pr sure 0i? air upon the undersurfaces o'l the planes, 'in such n manner as to iu'ipart lo the forwardends thereof, a lifting loroe.

The invention also aime` to provide finit-- able means whereby themachine may he ensilj.Y controlled,

The hare l to whichthe forward ends ol `the guide planes 10 nrc secured, arey essentially`straight and inclined slightlyY upwardly from their inner ends. Theframe bars 2 and .5 entend downwardly and forwardly from theirextremities in regular curves and have secured between them, the carrierplane ll. The ends of this plane are attached to the frame bars 6. TheGuide planes 10 are attached, as is clearly shown in Fig. l, to theframe bars 1, 3 and 7, said last mentioned bar being essentiallystraight and inclinedv downwardly and rearwardly. lt will be apparentthat an upward air pressure on the carrier plane 1l, will tend tosupport the aeroplane and the same pressure acting upon the guide planesl() will give to the machine a forward motion. The manner in which theguide lanes converge rearwardly also increases the tendency of themachine to a forwardmotion when acted upon by a lifting air pressure.

A car frame is supported by the frame bars 2 and 5. The car framecomprises top parallel bars 12, front downwardly converging bars 13, anangular centrally positioned bottom bar 14, and rearwardly convergingend bars 15. rlhe top bars 12 are connecte to the frame bars 2 and 5, bymeans of suitable straps 16 and the various bars forming the car frameare connected by couplings,

as clearly shown in Fig. 4. If desired, preferably canvas strips 17 maybe employed to form the walls ofthe car. A11 engine 18 is suitablysecured within the car and drives the shaft 19 to which is secured thefly-wheel 2O and pulleys 2l. Belts 22 are employed to drive thepropeller shafts 23, through the medium of the pulleys 24, which arerigidly secured upon sald shafts. The shafts 23 are secured to the bars12, by means of the hangers 25, said hangers being formed upon sleevemembers 26, which are secured in position by set screws 27. Theaeroplane may bel guided and vertically supported by the rudders 28 and29, which comprise preferably canvasv strips secured within suitableframes. A central rod 30 extends longitudinally of each of the ruddersthrough a suitable bearing 32. Steering rods 33 are connected to thecranks 32 and to suitable levers 34. These levers are positionedadjacent a seat 35 and are pivotally connected at their lower ends to abar 36, said bal being provided with two pairs of spaced ears 37. Itwill he seen that this construe tion perniits the operator to readilyshift the rudders either simultaneously or individually, so as to directthe machine as desired. l

Supporting wheels 38 are journaled. within the lower ends of standards39.
